IMPROVED MACHINE FOR MAKING EAVES-TROUGHS.

speeilieation forming part of Letters Patent No. 114,025, dated January 1, 1656.

- Yof Castile, in the county of Vyoming and State of New York, have invented a new and useful Machine for Making Tin or Metallic Eaves-Troughs; and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings, making a part of this specification.

Figure l is a. perspective view of the machine with the exception of the metallic movable receiving-clasp lc, aslettered below,which is elevated fer the purpose of being seen in the perspective view. Fig. 2 is a horizontal section of the same machine.

e a, Fig. l, are metallic ends or supporters ofthe machine.

is a circular wooden shaft having one side of it flattened, supported by gudgeons on each end7 extending` through a a.

c c are metallic rollers revolving on portions ofthe gudgeons on cach end of b, having slots or grooves for retaining in its place the metallic sliding bar d.

e is a handle for moving the metallic rods] f, which rods being connected with the sliding bar d retain it in the stays g fj.

It is a small metallic shaft turned by a crank on one end, connected by straps i t' and rod j j (which extend through portions of the rollers G 0) t0 the sliding bar d, for the p urpose 0f drawing it down, while each end of the sliding bar d is still retained in the slots ofthe rollers c c.

k is a metallic movable receiving clasp, which is retained by the square-headed bolts ZZ Z l, which extend through the clasp into the shaft Z), which clasp has agroove on the under side of it for retaining a bead.

Hode of operation: First, take sheet-tin or ,any other metal of proper qualifications and after cutting the sheets to a proper size and forming a bead on one edge connect together by the bead a requisite number to suit the length of the machine, and after adjusting the sliding bar d in the stays r/ f/ by the movable rods ff, so that there will be a requisite space between the sliding bar d and the wooden shaft I), and after turning the shaft b by the crank m, so that the movable clasp-7.', which is attached tothe clasp b, will be on the upper side of the shaft b and just back of the sliding bar d, which is now adjusted, and then after adjusting the said clasp 7.: up from the shaft b a requisite distance by means of the handle a, then slide the edge of the said tin, which has the bead formed upon it, between the slide-bar d and the shaft b under the groove of the clasp k. Then adj ust the movable clasp k by means of the handle a down upon the bead of the tin, so as to retain it. Then by moving the handle c so as to shorten the rodsff the sliding bar d drops in the slots of the rollers e c, and by turning vthe crank ofthe small shaft h the slide-bar d is drawn down; so as to compress the tin closely to the circular shaft b. Then by turning the circular shaft b by means of the crank mv over from you, (as you stand face to the machine and right hand to the crank,) the tin being fastened to the shaft 10 revolves with it, at the same time is pressed close to the shaft Z) by the sliding bar d until it has revolved over, so that the flat side of the shaft b is perpendicular, and also parallel with the face side of the sliding bar d. rlhe shaft b is then kept stationary by the dog o, which follows the rag-Wheel p. Non', then, by turning the small shaft h by its crank over from you, thereby drawing the slide-bar d down in the slots ofthe rollers c e, the tin is bent over at an angle, so as t0 fit the shape of the .circulaishaft b, forming eaves-trough with one side straight and perpendicular and the other side of a circular form, or what is termed quarter-circle eaves-trough. Now, by reversing the small shaft 71 thereby loosening the straps ii, it leaves the whole of the upper portion ofthe machine, with the trough formed and still upon it, to be turned either way at pleasure by means ofthe crank m or the handle a, for the purpose of soldering the different pieces of tin together while yet upon the machine, which is best done by standing behind the machine. Those scallops in the edge of the movable clasp l.: are to admit the soldering-iron down upon the tin to the bead on the tin, which is under the groove of the movable clasp la. The trough is then loosened from the machine by moving the adjustable clasp 7.", and taken out in lengths of some six feet, one person thereby making the abovedescribed eaves-trough with the facility of six good workmon in tho oldcouimonway, which stiuoted, arranged, und opomting substttuw cannot be surpassed 'for strength, regularity, tially as set forth. and durability.

Vhat I claim as my invention, and desire to secure by Letters Patent, is- XVitnesses:

The use ofthe semi-cylindrical shaft b, me- ANsoN HOWARD, tullio sliding bar (Z, and the end rollers e] con l JUDSON MALLORY.
